SPINNING MILL.

Be it known that I, THEOIIHLUS ZACH- ARIADIS, a subject of the King ofGreece, and residing at London, England, have invented a certain new anduseful Spinning Mill, of which the following is a specification. I

This invention relates to machines for spinning slivers, rovings and thelike into thread and winding the thread so formed on to bobbins or thelike. It has for its object the provision of an improved method andapparatus for the purposes set forth.

In machines of this kind, such as th mule and ring spinning frames, itis usual to feed the roving to the machine which spins it' and to windthe spun thread on bobbins in two separate operations.

The present inventionmainly consists in an apparatus forcarrying outsimultaneously and in a continuous and-uniform manner the operations ofspinning and winding.

The invention also consists in apparatus constructed and operatingsubstantially in accordance with the following description.

One way of carrying the invention into effect is described withreference to the ac colnpanying drawings, in which Figure 1 is asectional plan of the apparatus. V i

Fig. 2 is a transverse section on the line 2-2 of Fig. 1 in thedirection in which the arrows point.

Fig. 3 is a transverse section 011 the line 33 of Fig. l in thedirection in which the arrows point, and

Fig. 4 is an end elevation in part section of the mechanism for stoppingthe machine when the roving breaks.

In the figures, 1 and 2 are rectangular nietallic frameworks screwedtogether at their shorter ends by screws 8 and enclosing be tween theirlonger sides parallel slots 4: and 5.

To the opposite ends of these frameworks, discs 6 and 7 are fitted. Thedisc 7 is secured symmetrically, by means of screws 8, to a shorttubular axial shaft 9 and to the end of the rectangular frames 1 and 2,as shown. The tubular shaft 9 rotates in aball bearing 10 carried on abase plate 11.

The disc 6 is secured symmetrically by means of screws 12 to a toothedwheel 13 and to the end of the rectangular frames 1 and 2. The wheel 13is capable of rotation abouta shaft 14 to which is keyed a toothed 3,1922. Serial No. 598,891.

wheel 15. The shaft 14 is coaxial with the hollow shaft 9 and is carriedin ball bear ings 16 and 17 fixed to the base plate 11. A ball thrustwasher 17 is inserted between the toothed wheel 13 and the bearing 17 toreduce frictional losses.

A countershaft 18 mounted in ball bearings 19, 20 carries three spurwheels 21, 22, 21.) of which the wheel 21 meshes with the wheel 15attached to the shaft 1%; the wheel 22 meshes with the wheel 13 a tachedto the disc 6, while the wheel 23 engages with a spur wheel 24: attachedto a second countershaft 25.

The countershaft 25 is mounted in ball bearings 26 and 27 mounted 011the base 11 and carries besides the wheel 2% a second wheel 28 whichmeshes with a spur whee 29 mounted slidably upon a squared por tion 30'of a main driving shaft 31. The latter receives its motion from thesquared end 32 of the part A dog-clutch 33, 3a is inserted in the maindriving shaftin order to permit of starting and stopping the machinewhen required by disconnecting the continuously driven part 34: from thepart 30 and 31.

The main driving shaft 31, when the clutch 33 is in gear, drives throughthe wheels 29, 28 shaft 25, wheels 21 and 23, shaft 18 and wheels 21 and15 to the shaft 14 and wheels 22and 13 to the disc 6 and framework 1 and2.

The wheels 21 and 22 are of different di ameters and by a Suitablechoice of the sizes of the wheels of each of the two pairs 1.5, 21 and13, 22, any desired ratio of the relative speeds ofthe shaft lei and thedisc 6 with attached framework may be ob tained.

Firmly attached to the end of the shaft 14 which projects through thedisco and the framework 1 and 2 is a bevel gear wheel 35 which mesheswith a similar gear wheel 36 attached to a countershaft 37, which iscarried in a U-shaped bearing 38 attached to the disc 6, see Figure 2.The middle portion of the countershaft 37 is formed as a worm whichengages with a. worm wheel 39 formed on or attached to a double taperedshaft 40 which is carried in bearings 41, 4.2, as shown in Figure 1, inthe frame members 1 and 2. The bearing block 42 is removable from theframe and is locked in position by the slotted member 4-3 and the screw4%. The rotary motion of the shaft 40 is transill) ' 16, 47 mountedbetween the frame members .inanner is a box- 1 and 2 in bearings formedtherein. Attached by a squared end to the last-mentioned spur wheel 17is a shaft 48 which extends across the framework to a bearing 4-9 and onthis shaft is mounted a carefully machined cylinder 50. The bearing 19is secured similarly to 42. it bobbin 51 is carried in the forked ends52 ofa cradle 53 whose grooved sides 54 are adapted to slide along theframework 2. The cradle 53 carrying the bobbin 51 is urged towards thecylinder by means of springs whose ends engage with the slots of a recradle and which are anchored to the framework 1, 2 by means of the armsOne of the surfaces of the cradle :33 between "the ends 54 is curved, asshown in Figure 3, witi symmetrically placed recurred portions 58. Thewhole of the frames 1 and 2 together with their contents, cylinder 50,bobbin 51 etc, are enclosed from disc 6 to disc '7 by means of acylindrical cover made intwo parts, 59 and 60, and fastened, to thediscs and frame by rings 61, G2, 63 and 6-1 in such a manner that thepart of the cover attachedto the rings 62 and 61 when detached from thedisc 7 may he slid along the other part 60 attached to rings 61 and 63in order to expose the mechanism and to remove the bobbin 51 when filledwith thread. 7

Two metallic rings Sound 66, one on each side ofthe disc 7, areconnected together by bolts 67 and 68 which slide-through the frame endsand the disc 7. Two or more springs on bolts, not shown, which slidethrough the disc 7 alone and connect the rings and 66, serve to keep thering 66 in contact with the disc 1 until the spri are compressed by theend of the bobbin cradic 53 being forced against the extended ends ofthe ban er and (18 when the bobbin is filled with thread to a dot" ed doFixed to the base plate 11 in any suita iaped framework '39 which ugshaft :31 and extends try of the framework 1 and 2 as-shown in Fir-ares1 and 4.. A trigger 70 carrying a rol 71 sndes in one end of the frame69 and is reld normally by a compression spring T2 n contact with theinner side of frame 69, as shown in Figure 1, and is of such a lengththat the roller 71 nearly contacts with the rotating ring (38 on theframework 1 and 2.

The end, ofthe bolt 7 1 remote from the'trigger carries a embraces the d; beyondthe pcripl female screw-thread, shown in Figure 1,

which meshes with a. corresponding male delivered by "the cylinder.

consequently stops when the main machine stops. 7

Screwed to the side of the box 69 is a standard 77 carrying on a pivot78 on its upper forked extremity a rocker arm '79 (see Figure A wirering 80'is carried by one end of this rocking arm and is normally heldaxially in line with the centre of the hollow shaft 9 by the feedingroving, against the action'of a slightly overoalancing counterweight 81,linked to the other end of the rocking arm 79.

The counterweight is arranged to slide vertically in a guide 82"which issecured to a bolt 88 which is slotted to permit of movement across thedriving shaft 81. The end of the bolt 83 remote from the driving shaftslides in the box 69 and also through a slot 84 in the trigger 70.i-rsloping sur= face 85 is formed on the bolt 83 as shown and coactswith a sloping surface 86 on the side of the slot 8 1 in the trigger 70.An eccentric 87 rigid with the driving shaft 31 rotates'freely within anenlarged portion of the box 69 when the weight 81 is held up by theroving passing through the wire ring 80. Should the'roving fail to holdup the weight 81, e. g. if breakage of the roving should occur, theweight 81 descends by gravity to the bottom of the slide'82,isengaged'by the eccentric; 87 and moves together with'the bolt "83, withthe result that the sloping siiifaces85 and 86 cause the trigger to'move" until the slot 73" releases 'the'b olt'ii which disengages theclutch 83 a11d-34 by means of the male and female screw tlireads beforedescribed.-

' In normal operation thaprocess' is as follows: f v

- The roving is fed by. auxiliary *machines,- not shown; actuated by theshaft 31 by way" of the toothed :wheel 76. It then passes through thewire ring 80 of the stopping device and through the rotating hollowshaft 9. Fromthe inner end of this shaft theroving passes over thecurved edge of the cradle 53, laps the cylinder 50 and from' thecylinder is wound on the'bobbi'n 51. v 7

As the bobbin derives its motion from the circumference of the cylinderit is obvious that the bobbin will revolve at all times at the 7 correctspeed to absorb exactly and without strain the spun', thread which isThe pressure of the bobbin against the cylinder caused by the springspressing against the cradle 53 ensures an even laying of the spun threadupon the bobbin. As the bobbin fills, the cradle moves towards the stops67, 68 until at a predetermined filling the stops slide through the endof the casing and move the trigger until the bolt 74 is released by theslot 73 and the spinning mechanism is stopped as before described.

The stopping of the mechanism as a result of breakage of the roving hasalready been described.

The twist per unit length of. spun thread, it is clear, may be varied bysuitable dimensioning of the cylinder diameter and the ratio of theangular speed of the framework 1 and 2 about its axis to the angularspeed of the cylinder 50 about its axis. This latter ratio may be variedconveniently by varying the sizes of the difierential pairs of toothedwheels '91 and 15 and 22 and 13; but, of course, differential angularspeed variations may be made in any of the members of the train from theshaft l t to the cylinder 50.

The f ctthat the spinning and winding mechanism is enclosed, as shown,by the casing 59 and 60 renders the rotating mechanism, roving andthread immune from atmospheric influences, and reduces to a minimumfrictional losses due to air resistance to rotation. This feature alsoallows of the introduction of dry or humidified air through the hollowshaft 9.

The apparatus may be arranged to work on a horizontal axis, or, withsuitable modification of the gravity counterweight device, on a verticalaxis.
